Two trials, 31 and 29 days long, were conducted with the aim to pursue performance and health of pigs treated with different amounts of zearalenone and to investigate the feasibility of utilizing a modified clinoptilolite and esterified glucomannane in alleviating and/or preventing its harmful effects. Zearalenone exerted its negative effects on performance of pigs in concentrations used in the experiments, proportionally to the amount of toxin in the feed. Addition of adsorbents only partially alleviated the harmful effects of zearalenone in the feed. Signs of intoxication in female pigs, known as the estrogenic syndrome, were manifested by inflammatory changes of the external genital organs (vulvovaginitis) and with histological findings of epithelial hyperplasia and submucous oedema. Also nonspecific symptoms could be seed - gastrointestinal disorders followed by diarrhea. Use of adsorbents as toxin binders mostly alleviated these negative effects.
